Statistical Disclosure Control
LOW MODERATE HIGHRequirements NIST SOURCE
Manipulate numerical data, contingency tables, and statistical findings so that no individual or organization is identifiable in the results of the analysis.
Discussion (NIST Supplemental Guidance)
Many types of statistical analyses can result in the disclosure of information about individuals even if only summary information is provided. For example, if a school that publishes a monthly table with the number of minority students enrolled, reports that it has 10-19 such students in January, and subsequently reports that it has 20-29 such students in March, then it can be inferred that the student who enrolled in February was a minority.

Assessment
Assessment Objectives
- numerical data is manipulated so that no individual or organization is identifiable in the results of the analysis;
- contingency tables are manipulated so that no individual or organization is identifiable in the results of the analysis;
- statistical findings are manipulated so that no individual or organization is identifiable in the results of the analysis.

STIGs & CCIs
No STIG checks or CCI mappings are currently loaded for SI-19(5). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
